WebApr 11, 2024 · It was not a great leap for Binder to imagine the electrons moving along the metal and releasing a photon again at another location. ... His invisibility is based on heterodyning: the mixing of signals of two different frequencies to produce a higher or lower frequency output. Heterodyning is used to produce the audible output signals in radio ... WebThis method, called heterodyning, will be explained in detail in a future lesson. Today, I will only address the case where the unknown field is a weak quasi-classical state. ... If the photon flux Phi 2 of the local oscillator is known, it is clear that measuring the amplitude of the beat note allows us to determine the photon flux Phi 1. More ...

It turns out that for some operators homodyning is better than heterodyning when the mean photon number is sufficiently small. Finally, the robustness of the method to additive phase-insensitive …
WebOptical heterodyning has been observed at the single-photon level by recording the sinusoidal variation in the probability for detection of a photoelectron from a photomultiplier tube illuminated with a FM laser and a local oscillator laser. The single-photon character of the heterodyne process was demonstrated by observation of beat signals at total power … WebThe single-photon character of the heterodyne process was demonstrated by observation of beat signals at total power levels down to 6 times 10 to the -15th W where the spacing …
